Calling C library from C++ program

I have C++ based java native methods that works perfectly in passing String parameters back and forth with Java but wanted to know how could i load the C library from this C++ program and pass the parameters into it and get return string back from it.

The reason I want to not interact with C directly is because I need to pass 32 string parameters and handling them may be a challenge. If there is a easy way to handle 32 parameters in C that will be great.

The viewer will learn how to pass data into a function in C++. This is one step further in using functions. Instead of only printing text onto the console, the function will be able to perform calculations with argumentents given by the user.
